The invention discloses a combined type
resonator, in particular to a combined type piezoelectric
ceramic resonator which comprises a shell and a supporting frame arranged in the shell, wherein two leading wire feet are arranged outside the shell, one surface of the supporting frame is provided with a concave pit, opposite edges of the bottom of the concave pit are both provided with
electrode leading wires, and the two
electrode leading wires are respectively connected with the two leading wire feet, and the supporting frame is internally provided with a piezoelectric
chip which is pressed by a gland bush. The combined type piezoelectric
ceramic resonator is characterized in that one surface of the piezoelectric
chip is provided with a base plate, an
electrode layer is positioned between the base plate and one surface of a support base of the piezoelectric
chip to form an integer, the other surface of the piezoelectric chip is also provided with the electrode layer which is divided into two parts, the two parts are respectively connected with the two electrode leading wires, and a part of the electrode layer is connected with the electrode layer positioned between the piezoelectric support base and the base plate. The combined type piezoelectric
ceramic resonator is used for replacing an
LC circuit inside an ink box of a printer so that the ink box can be compatible for multi-type printers, thereby having more extensive range.
